1. a notebook and pencil in my shirt pocket are faster to open than a phone app

2. handwriting is faster than thumb typing

3. I can sketch an electrical diagram on paper way faster than anyone can with a stylus on some janky phone screen.

3.1) Even if there was a stylus/screen combination with the same haptics, fidelity, and input recognition speed as pencil on paper, it wouldn't be 0.78€

4. I can toss the notebook and diagrams to anyone working on a project with me with zero worry that they'll drop it, forget it, or look around in the rest of it

5. I can tear out a page and hand it to anyone instantly, instead of finding out what messaging app we have in common, copying (or screenshotting) the note and pasting it in an app

6. I can insert a note into a physical book, stick it to the inside of a toolbox lid, a wall next to an electrical junction, inside a breaker box, or any other surface, and always have location-aware reminders waiting for me when I need them.

7. With minimal environmental control, my notes are effectively immortal. I have notebooks of measurements and diagrams of most rooms, wall cavities, pipe runs, electrical runs, cable pulls, and dimensions of various equipment that have outlasted hard drives, backup tapes, and a few cloud storage companies.
